Layered pouring bearing platform and prefabricated pier column connecting structure and construction method
The invention discloses a layered pouring bearing platform and prefabricated pier column connecting structure and a construction method, and belongs to the technical field of bridge engineering. The purpose is to solve the inconvenience brought by the traditional construction technology of urban bridges in the aspect of connection of the prefabricated pier column and the bearing platform. According to the technical key points, improvement and innovation are carried out on the basis of traditional wet joint connection and slot type connection, and a prefabricated pier adjusting and supporting system is integrated. Layered pouring is conducted on a bearing platform, a post-pouring groove is reserved in the top of the bearing platform, connecting steel bars extend out of the bottom of a prefabricated pier, a prefabricated pier head is arranged, foundation bolts are embedded in the bearing platform to be connected with the prefabricated pier head, connection of the prefabricated pier and the bearing platform is achieved by pouring a post-pouring section of the bearing platform, and the perpendicularity of a pier column is adjusted through a threaded lifting sleeve. Compared with traditional bridge construction processes, the method has the advantages that: the installation precision is high, perpendicularity adjustment is easy and convenient, equipment hoisting time is short, connection is reliable, a single independent mold or a support does not need to be erected on the ground of a construction site, and the occupied area is small.
一种分层浇筑承台与预制墩柱连接构造及施工方法，属于桥梁工程技术领域。目的是在预制墩柱与承台连接方面，解决城市桥梁传统建设工艺带来的诸多不便。技术要点：本发明是在传统湿接缝连接与插槽式连接基础上进行改进创新，整合预制桥墩调节支撑系统。本发明是在承台分层浇筑并在承台顶预留后浇槽，预制桥墩底伸出连接钢筋并设预制墩头，承台预埋地脚螺栓与预制墩头连接，通过浇筑承台后浇段实现预制桥墩与承台的连接，墩柱垂直度采用螺纹升降套管进行调整。本发明相较于传统桥梁建设工艺，具有安装精度高，垂直度调式简便，吊装设备时间短、连接可靠，施工现场地面上无需单独立模或者搭支架，占地面积少等优点。
